1.1.12. MODELS ON REQUEST
The standard buzzers can be modified upon request in order to deliver a product, meeting
the requirements of the customer's application.
• Upon special request all standard models are also available in GREY, BLACK or GREEN
(khaki). Please add GREY, BLACK or GREEN to the part number if the required colour is
different from the one specified as standard.
• For applications under aggressive humid conditions, models containing a piezo element
covered with a protective coating are available. Add ACR to the part number.
The protective coating gives a complementary assurance against smog; all standard
models are perfectly waterproof (IP67) without the mentioned coating.
• Different pin terminal lengths, straight or bent can be custom manufactured.
• The frequency, indicated in the present catalogue, has an accuracy of ±15%. Standard
buzzers with an improved frequency accuracy (up to ±2%) are available upon special
